TACS enhancements for the Electromagnetic Transient Program [PDF]

Conference Proceedings Power Industry Computer Application Conference, 1993
Transient analysis of control systems (TACS) of the electromagnetic transient program (EMTP) has been enhanced in many ways. There are major changes in methods of ordering components to minimize the introduction of time step and history term errors. Initialization algorithms have been greatly enhanced to allow multiple frequency initialization.

A novel superimposed component‐based protection method for multi‐terminal transmission lines using phaselet transform

IET Generation, Transmission & Distribution, 2023
This paper presents a novel protection method for transmission lines that estimates the superimposed component phasor using phaselet transform. The phaselet transform computes the phasors over variable‐lenfgth data window at the instant of a fault, so it

Modeling of grain-oriented Si-steel and amorphous alloy iron core under ferroresonance using Jiles–Atherton hysteresis method

AIP Advances, 2018
Amorphous alloy is increasingly widely used in the iron core of power transformer due to its excellent low loss performance. However, its potential harm to the power system is not fully studied during the electromagnetic transients of the transformer ...
